Biological Systems Engineering: Papers and Publications

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus capable of measuring tractor hydraulic pressure and flow rate data was developed. The goal of this study was to determine if a hydraulic flow and pressure measurement device could be installed on the rear of a tractor to provide implement hydraulic power consumption at …


Fuel Consumption Models For Tractors With Partial Drawbar Loads, Bryan Jeffrey Smith Dec 2015

Fuel Consumption Models For Tractors With Partial Drawbar Loads, Bryan Jeffrey Smith

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Three models for predicting fuel consumption for agricultural tractors with partial drawbar loads were compared. Data were collected from eight John Deere tractors, JD 7230R (e23), 7250R (e23), 7270R (e23), 7290R (e23), 7290R (IVT), 8320R (16 speed), 8345RT (IVT), 8370R (IVT). The tractors were tested with 7 load levels per speed at four different travel speeds as close as possible to 4, 7.5, 10, and 13 km·h-1. The IVT tractors were operated in Auto mode and the geared tractors were shifted up three gears and throttled back to the same travel speeds as the IVT tractors. The 7 …


Dynamic Stability Of Two Tractor Front-End Loader Systems, Michael J. Bader, Linus R. Walton, Larry G. Wells Jul 1997

Dynamic Stability Of Two Tractor Front-End Loader Systems, Michael J. Bader, Linus R. Walton, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

A one-quarter scale model tractor and loader were designed, fabricated, and used in an experiment to evaluate two tractor-loader configurations relative to stability using roll angle as the means of assessment. The nonconventional loader system consisted of a conventional loader attached to a steerable carrier which in turn was attached to the tractor by the front axle and drawbar of the tractor. The stabilizing axle for the non-conventional loader system was the front axle as opposed to the conventional system in which the stabilizing axle was the rear axle. The experiment showed that the non-conventional loader had an inherent advantage …
